<p>The present invention concerns an apparatus for determining the condition of a wheel assembly (14) including at least a rim (20) and a tire (34). The apparatus comprises: an emitter source (22) for emitting radiation signals towards the wheel assembly, at least one detector (24) for receiving signals reflected from said wheel assembly in response to the emitted radiation signals, and a data processing device (26) connected to said emitter source and said at least one detector for processing data. The data processing device is configured to perform the steps of: obtaining height information including respective heights of a plurality of points located on the surface of the wheel assembly based on the signals received from the at least one detector, obtaining a three-dimensional data set indicative of said height information, and generating a surface profile of at least a part of the wheel assembly based on the three-dimensional data set, and displaying on a display means (30) said surface profile generated as a three-dimensional representation.</p> |
